Twenty-four companies now account for nearly three-quarters of the total value of Nigeria’s equities market, highlighting the growing concentration of market wealth among a relatively small group of large-cap stocks.
As of August 17, 2026, the companies had a combined market capitalisation of N117.01 trillion, representing 74.8 per cent of the Nigerian Exchange Limited (NGX) equities market, whose total capitalisation stood at N156.52 trillion.
The NGX market capitalisation has increased by N57.14 trillion, or 57.5 per cent, from N99.38 trillion at the end of 2025.
The sharp rise has been supported by strong gains across several sectors, particularly banking, consumer goods, industrial goods and energy. However, the concentration of market value means that the performance of a relatively small number of heavyweight stocks can have a significant influence on the broader market.
Large-cap stocks dominate the market
Dangote Cement Plc emerged as the most valuable company on the NGX, with a market capitalisation of N17.15 trillion, overtaking MTN Nigeria Plc.
BUA Foods Plc and BUA Cement Plc followed with N13.69 trillion each, while Aradel Holdings Plc was valued at N6.72 trillion.
Other companies among the most highly capitalised stocks included First Holdco Plc, HBM Nigeria Plc, Zenith Bank Plc, GTCO Plc, Stanbic IBTC Holdings Plc, Transcorp Hotels Plc, Presco Plc and Nestle Nigeria Plc.
The 24 companies are spread across several major sectors, with banks accounting for a significant portion of the list.
Banks maintain a strong presence
First Holdco led the banking stocks with a market capitalisation of N6.37 trillion, followed by Zenith Bank at N5.04 trillion and GTCO at N4.70 trillion.
Stanbic IBTC Holdings was valued at N2.56 trillion, while United Bank for Africa (UBA) stood at N1.99 trillion.
Access Holdings and Fidelity Bank had market capitalisations of N1.45 trillion and N1.38 trillion respectively. Ecobank Transnational Incorporated and Wema Bank followed with N1.27 trillion and N1.16 trillion.
The strong performance of banking stocks has been linked to improved investor sentiment and the sector’s recapitalisation programme, which has encouraged expectations of stronger balance sheets and greater capacity for future growth.
Consumer goods stocks remain prominent
BUA Foods was the largest consumer-related company on the list, with a market capitalisation of N13.69 trillion.
Presco followed at N2.40 trillion, while Nestle Nigeria was valued at N2.22 trillion.
Nigerian Breweries and International Breweries recorded market capitalisations of N2.10 trillion and N1.79 trillion respectively.
Although consumer-facing companies have benefited from expectations of improved operating conditions, the sector continues to contend with elevated production costs, inflationary pressures and weak household purchasing power.
Industrial giants drive market value
The industrial goods sector is another major source of market concentration.
Dangote Cement led the sector with a market capitalisation of N17.15 trillion. BUA Cement followed with N13.69 trillion, while HBM Nigeria had a market value of N5.38 trillion.
The size of these companies means that changes in their share prices can significantly affect overall market performance.
Energy stocks gain prominence
The energy segment also featured prominently among the largest companies.
Seplat Energy and Aradel Holdings each recorded market capitalisations of N6.72 trillion, while Geregu Power stood at N2.06 trillion and Transcorp Power at N1.65 trillion.
The growing representation of energy companies reflects increasing investor interest in Nigeria’s oil, gas and power businesses.
Market rally masks wide differences among stocks
Despite the strong performance of the broader market, individual stocks have produced vastly different returns.
Zichis Agro Allied Industries was the best-performing stock year-to-date as of August 17, gaining 1,744.22 per cent to N18.35 per share.
SCOA Nigeria rose 365.49 per cent to N33.05, while Infinity Trust Mortgage Bank gained 221.43 per cent to N11.25.
Berger Paints Nigeria increased by 207.50 per cent to N147.60, while Premier Paints appreciated by 204 per cent to N30.40.
Other major gainers included First Holdco, up 198.51 per cent to N140; Vitafoam Nigeria, which gained 153.04 per cent to N194; and HBM Nigeria, which rose 149.25 per cent to N334.
However, the market rally did not benefit all investors.
Sovereign Trust Insurance was the worst-performing stock, falling 50.39 per cent to N1.89.
Ellah Lakes declined 41.52 per cent to N8.10, while Guinea Insurance dropped 43.37 per cent to N0.76.
SUNU Assurances Nigeria fell 39.64 per cent to N3.32, while Austin Laz declined 39.06 per cent to N2.84.
Royal Exchange, Triple Gee & Company, Champion Breweries and Universal Insurance also recorded significant declines.
Transcorp Power fell 28.45 per cent to N219.60 despite the overall strength of the market.
Asset size paints a different picture
Market capitalisation is not the only measure of corporate size.
When companies are ranked by total assets, the picture changes considerably.
Ecobank Transnational Incorporated had the largest asset base in the second quarter of 2026, with total assets of N49.15 trillion.
First Holdco followed with N30.65 trillion, while Aradel Holdings recorded N10.88 trillion.
FCMB had total assets of N8.36 trillion and Oando N7.89 trillion.
Dangote Cement reported N6.62 trillion in assets, followed by MTN Nigeria with N5.97 trillion and Sterling Holdings with N4.67 trillion.
BUA Cement and BUA Foods recorded total assets of N1.92 trillion and N1.67 trillion respectively.
However, a large asset base does not necessarily translate into high profitability or strong shareholder returns. For financial institutions in particular, substantial assets are often accompanied by significant liabilities.
Negative equity raises investor concerns
The second-quarter balance sheets also highlight differences in financial strength.
Ecobank Transnational had shareholders’ equity of N3.17 trillion, while First Holdco recorded N3.63 trillion.
MTN Nigeria had positive equity of N930.61 billion, while Sterling Holdings reported N547.67 billion.
Dangote Cement had equity of about N3.17 trillion. Jaiz Bank and United Capital recorded positive equity of N93.6 billion and N187.09 billion respectively.
However, Aradel Holdings reported negative equity of N2.16 trillion despite having total assets of N10.88 trillion.
Oando also recorded negative equity of N530.45 billion against total assets of N7.89 trillion.
Negative equity does not automatically mean that a company is incapable of recovering, but it warrants closer examination of its debt obligations, cash flows, capital structure and plans to strengthen its balance sheet.
Analysts urge investors to look beyond the index
Market analysts have cautioned investors against interpreting the NGX’s strong headline performance as evidence of a broad-based improvement across all listed companies.
David Adonri, an analyst and Chief Executive Officer of Highcap Securities Limited, said the concentration of market value among a relatively small number of companies makes it important for investors to examine individual stocks rather than rely solely on the All-Share Index.
According to him, strong market performance can conceal significant differences in company fundamentals, earnings and valuations.
He also warned investors against buying stocks simply because they have recorded exceptional year-to-date gains, noting that substantial price appreciation does not necessarily correspond with an equivalent improvement in underlying business performance.
Another analyst at InvestData Consulting Limited advised investors to pay particular attention to companies with negative shareholders’ equity.
The analyst said investors should determine whether negative equity is temporary, whether management has a credible recapitalisation or restructuring strategy, and whether the underlying business generates enough cash to meet its financial obligations.
Analysts divided on investment prospects
Analysts’ recommendations also show that the market rally has created both opportunities and valuation concerns.
Of the 32 stocks assessed, 17 received Buy or Strong Buy ratings, while 12 were rated Sell or Strong Sell. Three stocks received Neutral ratings.
Among those rated Buy or Strong Buy were Aradel Holdings, Access Holdings, Dangote Cement, Dangote Sugar, FCMB, GTCO, Guinness Nigeria, HBM Nigeria, Honeywell Flour Mills, Nigerian Breweries, Nestle Nigeria, UACN, Transcorp Corporation, UBA, Zenith Bank and Cadbury Nigeria.
Stocks receiving Sell or Strong Sell recommendations included BUA Cement, BUA Foods, Conoil, First Holdco, International Breweries, Julius Berger, Okomu Oil, Presco, PZ Cussons, Stanbic IBTC, TotalEnergies Marketing and Unilever Nigeria.
Fidelity Bank, Ecobank Transnational Incorporated and NASCON Allied Industries were rated Neutral.
The divergence in recommendations suggests that investors are becoming more selective as valuations rise.
Analysts said investors should focus on earnings growth, dividend potential, debt levels, cash generation and return on equity when assessing individual stocks.
Concentration presents both opportunity and risk
The dominance of 24 companies in the NGX’s total market value underscores the growing influence of large-cap stocks on Nigeria’s equity market.
For investors, the strong market rally presents opportunities, but it also highlights the importance of distinguishing between rising share prices and improving business fundamentals.
A stock market can deliver a strong headline return while individual companies experience very different outcomes.
With nearly three-quarters of market capitalisation concentrated in a small group of companies, movements in these stocks will remain critical to the direction of the NGX.
The message for investors is therefore clear: a rising market is not necessarily a uniformly attractive market. Understanding valuations, earnings, balance sheets and cash flows remains essential when deciding where to invest.
